Fan control API in TivaWare 2.1.1.71

The TivaWare Peripheral Driver Library User's Guide Chapter 12 describes a fan control API driver contained in the files fan.h and fan.c.  In my TivaWare 2.1.1.71 installation, I don't see those files.  The file hw_fan.h exists, but it does not have any defines in it.  Are the fan API files available elsewhere?

    Hello John,

    That is correct, that the mention of the same in the document is there and the hw_fan.h is there as well. The feature shall not be available on any of the existing devices in production and the peripheral has not been added to the list of devices yet which will support the feature as a new part number has to be made.

    Can you let me know what potential use of the same are you looking at?

    Regards

    Thank you for the timely reply. I am just learning to program these devices, and making a multi-channel PC fan controller for my home PC was one project I considered doing to gain some hands-on experience.

    Hello John,

    If the PC Fan you are using is a 3 wire Fan, then a timer in PWM mode would be suitable. If it is a 4 wire fan then a timer in PWM mode for control and another timer in Capture Time Mode would be a suitable replacement.
